Sampling with texture gather. 30 + Rendering tests with border value exceeding the representable range of 31 the texture format. 32 + Sampling depth textures with mode set to COMPARE_REF_TO_TEXTURE. 33 34 Excludes: 35 + Sampling with mipmaps 36 + Sampling with texture 2d arrays or cubemaps 37 + Texture swizzle cases 38 + Exhaustive testing of all s/t/r wrapping mode combinations 39 40 Description: 41 42 Texture border clamp cases test functionality added in 43 EXT_texture_border_clamp extension. Tests set up a texture with a certain 44 format, set border color to certain value, set one or more wrapping modes to 45 CLAMP_TO_BORDER, and then proceed to render the texture to screen. The 46 rendering result is then verified. Test cases also generate a reference image 47 which may be useful when evaluating results. 48 49 In formats.* subgroup, all GLES31 texture formats are tested. Each format is 50 tested with power-of-two and non-power-of-two texture sizes using NEAREST and 51 LINEAR filtering, and texture-gather fetching. 52 53 In range_clamp.* subgroup, border color components are set to values that are 54 not in the representable range of the internal format. The effective value is 55 expected to be clamped to the valid range. 56 57 In sampler.* subgroup, texture border color and wrapping mode are set using 58 a sampler state. 59 60 In per_axis_wrap_mode.*, texture wrap mode is not same in all S, T, and R 61 directions. Wrapping is tested for 2D and 3D textures with multiple formats 62 and with different sampling modes. 63 64 In depth_compare_mode.*, depth texture border values are tested with compare 65 mode set to COMPARE_REF_TO_TEXTURE. 66 67 In unused_channels.*, border color has non-zero values in components that are 68 not representable in the target formats. These components are expected to have 69 no effect. 70
